Let’s Know About Components of Motherboard


A motherboard is a circuit board for a computer system, often known as a logic board or mainboard. The motherboard is the most critical component in a computer system because it controls all of the other components and connects them together. The motherboard connects several parts like ROM, CPU, RAM, PCI slots, USB ports, and other components. The controller’s device, such as a DVD hard drive, mouse, and keyboard, is also connected to the motherboard. The motherboard is used to start the computer system, and these components serve as the system’s backbone.

Motherboard Components

Some of the most significant motherboard components are defined in the following section:

1. Mouse and keyboard

There are two kinds of mouse and keyboard connectors. The first connector is known as PS/2, while the second is known as USB.

2. Universal Serial Bus (USB) (USB)

The USB port is used to connect the computer. A USB port connects a variety of devices in a computer system, including a keyboard, mouse, camera, scanner, printer, and other devices. A USB port’s primary function is to link peripheral devices and computer motherboards. The fundamental advantage of a USB port is that peripheral devices connected to the computer system can be inserted or removed without requiring a system restart.

3. The parallel port

The parallel port was once used by obsolete printers to connect to the computer system. Numerous wires are used in parallel ports to send and receive multiple bits of data in a single instance. On the other hand, Serial ports only use one wire at a time. The parallel port employs a 25-pin female DB type connector.

4. CPU processor

The central processing unit is the processor that manages all of the computer system’s functions. The central processing unit manages the overall flow of tasks and functions. The central processing unit of a computer system is referred to as the computer system’s brain.

5. Memory slots

RAM slots are used to connect RAM (memory) in a computer system. In most computer systems, there are two RAM slots, however, there may be four or more slots on the white x570 motherboards to enhance the computer system’s memory.

6. Floppy Disk Controller

The earlier motherboard chip includes a 34-pin ribbon connector for connecting the computer to a floppy drive. One end of this ribbon cable is directly attached to the computer system, while the other end is connected to the motherboard.

7. The IDE controller

Integrated drive electronics (IDE) is a sort of component that is given for hard drive control and is also known as ATA or Parallel ATA. The IDE controller is not supported in today’s computer systems.

8. PCI bus

A peripheral component interface is the complete form of PCI. The PCI slot is mostly used to install expansion cards on computers. Other PCI devices, such as sound cards, network cards, video cards, modems, and other devices, can also be connected. PCI expansion slots are not supported in today’s computer systems.

9. ISA port

The term “industry-standard architecture” (ISA) refers to the standard architecture for expansion buses. The ISA slot was created to link input devices and modems.

10. Battery for CMOS

The CMOS battery stores the BIOS settings on the motherboard. The CMOS battery can also be used to store time and data.

11. AGP port

AGP (Accelerated Graphics Port) is a type of computer slot used to connect a video card to a system. This slot is a high-speed slot, which allows for fast data transfer.

12. CPU socket

The CPU slot is a sort of connection that connects the central processor unit to the computer system’s motherboard.

13. Slot for power supply

The power supply slot is used to supply power to the computer system so that it can start and perform its functions. The overall power supply provided to the system is around 110 ac power. The power supply type connector has a total of 20 pins that are used to maintain the computer system’s power supply.

The motherboard is a sort of circuit board that is installed in a computer system and connects all of the computer system’s components. The motherboard is regarded as the computer system’s backbone. There are various motherboard configurations that can be distinguished based on budget, needs, requirements, and speed. The motherboard is regarded as a primary hub via which all computer devices are connected.
